CarVinGroot ShanghaiShi / The rep told to wait, but after 3 weeks still no delivery of order

I ordered the shoes for my son from the company CarVinGroot ShanghaiShi. I got the confirmation email, but the order hasn’t been delivered on the estimated date. I contacted the rep, who told me to be patient and explained that the plane was delayed and therefore all the stuff. After 3 weeks I heard the same ###. Stay away from these jerks and post comments if you can help me.
